This patch only adds the path of a task that is not queued, which leaked before. If the time is ahead, the runtime left fits the task's own bandwidth, so a task that comes back gains nothing. If it is past, the bandwidth goes with the parameters. The cost is the 0-lag time from before the boost: switched_to_dl() cancels the timer that held it. So the release can come up to one period of the task early, or late until the donor's deadline. Keeping that time across a boost would change how the inactive timer treats a boosted task. I would leave that out of this series. Thanks, Mathieu -- Mathieu Desnoyers EfficiOS Inc. https://www.efficios.com
